- Subject: bootstrap failure with HP's C compiler on trunk: PR 12186 returns
The trunk fails to bootstrap on HP due to an HP compiler bug. This
is the same issue as bootstrap/12186, but it has arisen in a different
place: the compiler crashes if the |= operator is applied to a bitfield.
Here's a patch. Should I re-open PR 12186 or make a new PR?
